Could O.J. Simpson be Khloe Kardashian's biological father? No way say the K's

If the face fits, he must be it!

That's basically what the National Enquirer is saying in a report that claims O.J. Simpson is Khloe Kardashian's real father, because Khloe closely resembles Sydney Simpson, O.J.'s daughter with Nicole Brown.

"O.J. Bombshell: 'I'm Khloe's REAL Dad!" the cover reads. "Shocking truth about O.J. & Kardashian mom."

Khloe's father, Robert Kardashian, was one of O.J.'s attorneys during his murder trial, where he was famously acquitted from murdering his wife largely because a glove used in the murder did not fit his hand in court.

Khloe, Kim, and mom Kris Jenner all took to Twitter to laugh off rumors that Simpson was Khloe's real father. But it wasn't the first time claims were made that Khloe's dad was someone other than Robert Kardashian.

Earlier this year, the second wife and widow of the late Robert Kardashian made some seriously salacious claims against the Kardashians in a bombshell interview with Star magazine.

Jan Ashley, 63, is the woman who married Kardashian after his divorce from Kris Jenner was finalized. She claimed that before his death from cancer in 2003, he told her that Khloe is not his daughter.

“Khloe is not his kid – he told me that after we got married,” Ashley told Star. “He just kind of looked at me and said [it] like it was a matter of fact. He said, ‘Well, you know that Khloe’s not really a Kardashian, don’t you? And I said … ‘OK,’ and that was it.”

The rumors have plagued Khloe and her family for years, with one episode of “Keeping Up With the Kardashians” even featuring the 27-year-old questioning if she was adopted.

“Khloe brought it up all the time,” Ellen Kardashian, who married the lawyer after his split with Jan Ashley and just two months before his death, said to the magazine. “She looked nothing like the rest. She was tall, had a different shape, light hair, curly hair. Didn’t look anything like the other three children.”

Kris Jenner also came forward in her memoir to confess that she had an affair during her marriage to Robert Kardashian. And both Jan and Ellen claim it was no secret that Kris had strayed.

“Robert did question the fact that Khloe was his,” Ellen told the magazine. “Any normal man would if they knew their wife had cheated on him … But he never would have considered a DNA test. He loved her very much.”
